摘要
分析了沈阳红阳三矿煤中各种硫分、灰分和不同密度级的全硫 ,并研究了硫分与粒度、硫分与密度、硫分与灰分及硫分布率与密度等的关系·指出无机硫占煤中全硫质量分数的77 39% ,是该煤中硫的主要形态 ;煤中硫的分布是均匀的 ,不随粒度、密度、灰分的变化而变化 ;煤样中黄铁矿呈细小颗粒浸染于煤有机质中 ,用常规方法脱除比较困难 ;有机硫的质量分数约为2 0 % ,且目前还没有很好的脱除方法 ,故暂不考虑其脱除问题·
All kinds of sulfur,ash,total sulfur with different density in Coal of Hongyang Third Mine in Shenyang were studied. The relations of total sulfur and size, total sulfur and density, total sulfur and ash, density and distribution of sulfur were studied. The mineral sulfur whose content is 77 39% in the total sulfur of the coal is the major modality,and the sulfur of the coal samples is well distributed. It doesn't change with the particle,the density and the ashes. The pyritic sulfur immerges in coal with small grain and is difficult to be removed by common methods. Organic sulfur's content is 20% in the total sulfur of the coal.
